ACK.

But the various layout managers may have different ways to
access/signal the plugins. That is where the wrappers come
in, they mediate between what the layout manager thinks it
wants to do and what the non-plugin widget code (in wxpython/)
does.

Sure, if "your" layout manager wants to do it that way, fine.
That shouldn't affect "my" layout manager, however. Else we'd
not need to try and separate them.

If you do that you forego the ability to reuse the functional
GUI part in custom clients by hardcoding the assumption that
this functional part of the GUI is a layout manager plugin, or
even a notebook plugin. Again, the *functional* part couldn't
care less whether it's instantiated in a plugin wrapper or in
a simple standalone frame or whatever.

Sure, see above. "Your" layout manager may do as it pleases.

One thing, can you post a screenshot ? I am not convinced that
I understand the look of "your" layout manager. Are we sure
Richard agrees that that is what he intended ?

Huh ? How ?

This makes a lot of sense, we just haven't gotten around to it.

As they are now automatically. I agree, however, that the
get_plugin_load_list tries to be overly smart (my fault). I
will fix that.
